The photo at left is the xo-1.5. For the most part it is identical to the xo-1.The only real difference (besides the color) is that the 1.5 was designed for use by secondary school students. The membrane keyboard has been replaced with a standard clicky one (like any other laptop.)
BTW, the new color comes from the fact that Uruguay were the first to adopt the xo-1.5 (blue and white are their national colors). It also makes it easier to differentiate between the 2 models.
So why am I covering this? Well I've been wanting to do more posts on the OLPC project. Some of the topics are deeply technical and need a little background. This seemed like a good place to start.

"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
